AI Thread Summary
The discussion revolves around the reactions of silver nitrate with chloride (Cl-) and bromide (Br-) ions in water. Participants clarify that both AgCl and AgBr precipitates can appear similar, with AgBr having a slight yellowish tint compared to the white of AgCl. There is a concern about the reliability of using precipitate color alone for distinguishing between the two, suggesting that this method may not be definitive for analysis. The conversation highlights the importance of understanding the visual differences in precipitates when conducting chemical tests.

I don't quite understand this part:

We were expecting to have the Cl- solution, and tap water look the same. However, the tap water and the Br- solution looked the same (after adding silver nitrate).

Are you reffering to the solutions of chlorine and bromine or the AgCl and AgBr formed?

AgCl and AgBr look quite similar, but AgBr is slightly yellowish in comparion to AgCl.

And you were judging this just based on precipitate color? This doesn't seem like a very definitive method of analysis.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
